Hello again,

Just a short info that the root cause of the SIGSEGV is because the
usbfs is not mounted, thus libusb_init() call failed. Unfortunately
the return value of libusb_init() was not checked, so the rest of the
API calls accessed dangling pointer including the lock for pthread, it
should have been initialized before.

Now it is fixed.

Thanks for your time.

Best regards,
DWI
